具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio， NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系 统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
网络设备110可以为小区提供服务，终端设备120通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备110进行通信，该小区可以是网络设备110(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括例如城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在小区搜索过程之后，终端设备已经与小区取得了下行同步，因此终端设备可以接收下行数据。但终端设备只有与小区取得上行同步，才能进行上行传输。终端设备可以通过随机接入过程(Random Access Procedure)与小区建立连接并取得上行同步。
在NR系统中，可以支持两种随机接入方式：基于竞争的随机接入方式(如图2所示)和基于非竞争的随机接入方式。为了便于理解本申请实施例 的方案，下面结合图2简单介绍基于竞争的四步随机接入过程：
步骤1，终端设备向网络设备发送Preamble(也即message1，Msg1)。
其中，随机接入前导码也可以称为前导码、随机接入前导码序列、前导码序列等。
具体而言，终端设备可以选择物理随机接入信道(Physical Random Access Channel，PRACH)资源，PRACH资源可以包括时域资源、频域资源和码域资源。接下来，终端设备可以在选择的PRACH资源上发送选择的Preamble。
可选地，终端设备可以通过随机接入资源配置获取到发送Preamble的PRACH资源。比如，小区使用的随机接入资源配置信息可以在系统消息中指示给接入的终端设备，从而终端设备可以通过指示的随机接入资源配置信息，确定PRACH资源的时域信息、频域信息和码域信息。
其中，随机接入资源配置可以包括256种配置，包括但不限于Preamble格式、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内PRACH时隙的格式、PRACH时隙内PRACH时机的个数、PRACH时机持续时间等。
步骤2，网络设备向终端设备发送随机接入响应(Random Access Response，RAR，也即message2，Msg2)
网络设备检测到有终端设备发送Preamble后，可以向终端设备发送RAR，以告知终端设备在发送Msg3时可以使用的上行资源信息。其中，RAR中可以包括Preamble的标识、定时提前(Time Advance，TA)、上行授权(UL grant)、临时小区-无线网络临时标识(Temporary Cell Radio Network Temporary Identifier，TC-RNTI)等信息。
相应地，对于终端设备来说，终端设备向网络设备发送Preamble后，可以开启一个RAR窗口，在该RAR窗口内根据随机访问无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)检测对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)。若终端设备检测到RA-RNTI加扰的PDCCH后，可以获得该PDCCH调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。其中，该PDSCH中包括Preamble对应的RAR。
如果在此RAR窗口内没有接收到网络设备回复的RAR，则终端设备可以认为此次随机接入过程失败。应理解，终端设备和网络设备都需要唯一地确定RA-RNTI的值，否则终端设备就无法解码RAR。
可选地，本申请实施例中，RA-RNTI可以通过收发双方都明确的Preamble的时频位置来计算RA-RNTI的值。比如，与Preamble相关联的RA-RNTI可以通过公式(1)计算：
RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id  (1)
其中，s_id为PRACH资源的第一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的索引(0≤s_id<14)，t_id为一个系统帧 中PRACH资源的第一个时隙的索引(0≤t_id<80)，f_id为频域中PRACH资源的索引(0≤f_id<8)，ul_carrier_id为用于传输Preamble的上行载波(0表示NUL载波，1表示SUL载波)。对于FDD而言，每个子帧只有一个PRACH资源，因此，f_id固定为0。
步骤3，终端设备发送Msg3。
终端设备在收到RAR消息后，判断该RAR是否为属于自己的RAR消息，例如终端设备可以利用前导码索引进行核对，在确定是属于自己的RAR消息后，可以在RRC层产生Msg3，并向网络设备发送Msg3，其中，Msg3需要携带终端设备特定的临时标识信息等。
步骤4，网络设备向终端设备Msg4。
Msg4中可以包括竞争解决消息以及为终端设备分配的上行传输资源。终端设备接收到网络设备发送的Msg4后，检测Msg4中是否包括终端设备在Msg3中包括的终端设备特定的临时标识。若包括则表明终端设备随机接入过程成功，否则认为随机接入过程失败，终端设备需要再次从步骤1开始发起随机接入过程。
四步随机接入的时延比较大，对于5G中的低时延高可靠场景是不合适的。考虑到低时延高可靠相关业务的特点，提出了两步随机接入过程的方案。如图3所示，在两步随机接入过程中，简单的说，相当于将四步随机接入过程的第一步和第三步合并为两步随机接入过程中的第一步，将四步随机接入过程的第二步和第四步合并为两步随机接入过程中的第二步。
也就是说，在两步随机接入过程中，终端设备向网络设备发送Msg A，Msg A包括Preamble和PUSCH，如图4所示。之后，网络设备向终端设备发送Msg B，Msg B包括PDCCH和PDSCH。
应理解，图3仅仅是两步随机接入过程的一种具体实现方式，不应对本申请的保护范围构成限定。
在单小区配置了两个上行载波或者配置了载波聚合的情况下，在同一传输时刻，终端设备可能在多个上行载波上发送信号，如发送PUSCH、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、PRACH、探测参考信号(Sounding Reference Signal，SRS)等。终端设备可以根据定义的信号的功率计算方法分别确定要发送的信号的发射功率。然而，终端设备的最大发射功率是有限的，如果终端设备的上行各个载波上各个上行信道或信号的功率之和大于终端设备的最大发射功率，则需要对部分或者全部的上行信道或信号的功率进行一定程度的功率压缩，以满足终端设备的最大发射功率进行发送。
在5G NR中定义了不同的信号之间进行功率分配的优先级，即功率分配优先级顺序，当信号的功率之和超过终端设备的最大发射功率时，终端设备可以根据规定的功率分配优先级顺序进行功率分配，即优先将功率分配给优先级高的信号，而优先级低的信号的功率可能会被压缩，以使终端设备的发射功率小于或等于终端设备的最大发射功率。
版本15(Rel)中定义的功率分配优先级顺序如下，其中，优先级从高到低依次排列：
在主小区(Primary Cell，PCell)传输的PRACH(PRACH transmission on the PCell)；
承载混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)-肯定应答(Acknowledgment，ACK)信息，和/或，调度请求(Scheduling Request，SR)的PUCCH，或承载HARQ-ACK信息的PUSCH(PUCCH transmission with HARQ-ACK information and/or SR or PUSCH transmission with HARQ-ACK information)；
承载信道状态信息(Channel State Information，CSI)的PUCCH或承载CSI的PUSCH(PUCCH transmission with CSI or PUSCH transmission with CSI)；
未承载HARQ-ACK信息或CSI的PUSCH(PUSCH transmission without HARQ-ACK information or CSI)；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输(SRS transmission,with aperiodic SRS having higher priority than semi-persistent and/or periodic SRS,or PRACH transmission on a serving cell other than the PCell)。
可以看到，PCell上传输的PRACH的功率分配优先级最高，SRS或者非PCell上传输的PRACH的功率分配优先级最低。
在载波聚合场景下，当不同载波的信号或者信号的功率分配优先级相同时，终端设备可以优先将功率分配给主小区组(Master Cell Group，MCG)或者辅小区组(Secondary Cell Group，SCG)的PCell上的信号，其次是SCG的PCell。并且MCG和SCG的PCell之间，优先分配给MCG的PCell，其次是SCG的PCell。在单小区配置了两个上行载波的场景下，终端设备可以优先将功率分配给用于传输PRACH的载波上的信号。如果没有配置发送PUCCH的载波，则终端设备可以优先将功率分配给非补充上行载波(Non-Supplementary UL Carrier)。
然而，在两步随机接入过程中，当终端设备同一传输时刻在多个上行载波上发送多个信号，该多个信号包括第一消息中的PUSCH，且该多个信号的发射功率之和大于终端设备的最大发射功率时，终端设备如何确定第一消息中的PUSCH的发射功率，目前还没有明确的规定。鉴于此，本申请实施例提出了一种功率分配的方法，当终端设备在同一传输时刻发送多个信号，且该多个信号的发射功率之和大于终端设备的最大发射功率时，可以确定第一消息中的PUSCH的发射功率。
图5是根据本申请实施例的功率分配的方法300的示意性流程图。图5所述的方法可以由终端设备执行，该终端设备例如可以为图1中所示的终端设备120。如图5所示，该方法300可以包括以下内容中的至少部分内容。
应理解，方法300可以应用于单小区配置了多个上行载波的场景中，也 可以应用于载波聚合的场景中，还可以应用于其它场景中，本申请实施例对此并不限定。
在310中，终端设备确定第一传输时刻的总发射功率，其中，第一传输时刻的总发射功率为多个待发送信号的发射功率之和，该多个待发送信号包括第一PUSCH，第一PUSCH属于第一消息，第一消息包括Preamble和第一PUSCH。
在本申请实施例中，第一消息包括Preamble和第一PUSCH可以理解为：终端设备在向网络设备发送Preamble和发送第一PUSCH之间，网络设备与终端设备之间没有其他消息，和/或，网络设备可以针对Preamble和第一PUSCH同时向终端设备发送随机接入响应。
在本申请实施例中，第一PUSCH可以承载用于区分终端设备的信息，如终端设备标识、无线网络临时标识(Radio Network Temporary Identifier，RNTI)等。此外，第一PUSCH还可以承载该随机接入的触发事件。其中，随机接入过程通常可以由以下事件触发：
(1)初始接入(Initial Access)。
终端设备可以从无线资源控制(Radio Resource Control，RRC)空闲态(RRC_IDLE态)进入RRC连接态(RRC_CONNECTED)。
(2)RRC连接重建过程(RRC Connection Re-establishment procedure)。
(3)切换(Handover)。
此时，终端设备处于连接态，需要与新的小区建立上行同步。
(4)RRC连接态下，下行数据或上行数据到达时，上行处于“不同步”状态(DL or UL data arrival during RRC_CONNECTED when UL synchronisation status is"non-synchronised")。
(5)RRC连接态下，上行数据到达时，没有可用的PUCCH资源用于调度请求(Scheduling Request，SR)传输(UL data arrival during RRC_CONNECTED when there are no PUCCH resources for SR available)。
(6)SR失败(SR failure)。
(7)RRC在同步配置时的请求(Request by RRC upon synchronous reconfiguration)。
(8)终端设备从RRC非激活态过渡(Transition from RRC_INACTIVE)。
(9)在辅小区(Secondary Cell，SCell)添加时建立时间对齐(To establish time alignment at SCell addition)。
(10)终端设备请求其他系统信息(Other System Information，OSI)。
(11)终端设备需要进行波束失败的恢复(Beam failure recovery)。
针对不同的随机接入触发事件，第一PUSCH承载的内容可以不同。
例如，对于初始接入的场景，第一PUSCH可以承载RRC层生成的RRC连接请求消息(RRC Setup Request)。此外，第一PUSCH还可以承载例如终端设备的5G-服务临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)或随机数等。
又例如，对于RRC连接重建场景，第一PUSCH可以承载RRC层生成的RRC连接重建请求消息(RRC Reestablishment Request)。此外，第一PUSCH还可以承载例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)等。
又例如，对于切换场景，第一PUSCH可以承载RRC层生成的RRC切换确认消息(RRC Handover Confirm)，其携带终端设备的C-RNTI。此外，第一PUSCH还可承载例如缓冲状态报告(Buffer Status Report，BSR)等信息。对于其它触发事件例如上/下行数据到达的场景，第一PUSCH至少可以承载终端设备的C-RNTI。
可选地，上述内容中的多个待发送信号可以包括但不限于：PUSCH、PUCCH、PRACH、SRS等。其中，PDCCH还可以是增强的物理下行控制信道(Enhanced Physical Downlink Control Channel，EPDCCH)、机器类通信物理下行控制信道(Machine Type Communication Physical Downlink Control Channel，MPDCCH)、物理副链路控制信道(Physical Sidelink Control Channel，PSCCH)或窄带物理下行控制信道(Narrowband Physical Downlink Control Channel，NPDCCH)，本申请实施例对此不作具体限定。
以待发送信道为PUCCH进行说明，应理解，发送信道可以理解为：发送PUCCH承载的数据，或者，将传输资源分配给PUCCH，或者，在传输资源上传输PUCCH上的数据。
在本申请实施例中，终端设备确定第一传输时刻的总发射功率的方式可以有很多，本申请对此并不限定。例如，终端设备可以根据现有的信号的功率计算方法分别计算待发送信号的发射功率，之后，将各个待发送信号的发射功率进行求和即可得到第一传输时刻的总发射功率。
需要说明的是，第一传输时刻的总发射功率不是终端设备在第一传输时刻的实际发射功率，第一发射时刻的总发射功率大于或等于第一传输时刻的实际发射功率。
在320中，当第一传输时刻的总发射功率大于终端设备的第一最大发射功率时，终端设备根据功率分配优先级顺序，确定第一PUSCH的第一发射功率。
可选地，第一最大发射功率可以是终端设备的绝对最大发射功率P CMAX(i)，或者也可以绝对最大发射功率的线性值(Linear Value)，即标准中的
Figure PCTCN2019081812-appb-000001
当第一最大发射功率为
Figure PCTCN2019081812-appb-000002
时，在单小区配置了两个上行载波或者配置了载波聚合的情况下，如果在传输时机i中用于PUSCH/PUCCH/PRACH/SRS传输的终端设备的总发射功率将超过
Figure PCTCN2019081812-appb-000003
Figure PCTCN2019081812-appb-000004
为P CMAX(i)的线性值，终端设备可以根据功率分配优先级顺序对PUSCH/PUCCH/PRACH/SRS分配发射功率，以使终端设备在传输时机i的 每符号中的发射功率小于或等于
Figure PCTCN2019081812-appb-000005
当第一传输时刻的总发射功率大于终端设备的第一最大发射功率时，终端设备需要对全部或部分的待发送信号进行压缩，即重新确定待发送信号的发射功率，包括重新确定第一PUSCH的发射功率，以满足终端设备的第一最大发射功率。
在重新确定第一PUSCH的发射功率时，终端设备可以根据功率分配优先级顺序，确定第一PUSCH的第一发射功率。其中，第一PUSCH的第一发射功率可以小于或等于重新确定发射功率之前的第一PUSCH的发射功率。
在一种可能的实施例中，功率分配优先级顺序可以与前述内容的功率分配优先级顺序(为了描述方便，称为第一功率分配优先级顺序)相同。
在四步随机接入中，PRACH，也就是Msg1的功率分配优先级最高，而第一PUSCH，也就是Msg3的功率分配优先级较低。这是因为在四步随机接入中的Msg3可以支持重传，即使因为第一PUSCH进行了功率压缩而没有被网络设备正确接收到，则网络设备可以使用TC-RNTI扰码的下行控制信息(Downlink Control Information，DCI)格式(format)0_0来调度Msg3的重传。
然而在两步随机接入过程中，第一消息包括四步随机接入过程中的Msg1和Msg3，即包括Preamble和第一PUSCH两部分。如果使用第一功率分配优先级顺序，当第一消息中的第一PUSCH部分的功率由于其功率分配的优先级较低而被压缩，则可能第一消息不能被网络设备正确接收，从而会造成第一消息的重传，增加了两步随机接入的时延。此外，由于重传的功率攀升，该实施例可能增加额外的上行干扰和随机接入资源的浪费。
因此，本申请实施例提出了另一种实施例，在另一种可能的实施例中，终端设备可以根据第二功率分配优先级顺序，确定第一PUSCH的第一发射功率。
应理解，在本申请实施例中，“第一”和“第二”仅仅为了区分不同的对象，但并不对本申请实施例的范围构成限制。
在一种实现方式中，第二功率分配优先级顺序可以包括第一PUSCH的功率分配优先级高于以下中的至少一项功率分配优先级：未承载HARQ-ACK信息的PUSCH的功率分配优先级、未承载CSI的PUSCH的功率分配优先级。
具体地，作为一种示例，第一PUSCH的功率分配优先级可以与在PCell传输的PRACH的功率分配优先级相同。此时，第二功率分配优先级顺序可以如下所示：
在PCell传输的PRACH，或者在PCell传输的第一PUSCH(PUSCH transmission in Msg A of 2 step RACH on the PCell)；
承载HARQ-ACK信息和/或SR的PUCCH，或承载HARQ-ACK信息的PUSCH；
承载CSI的PUCCH或承载CSI的PUSCH；
未承载HARQ-ACK信息或CSI的PUSCH；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输。
作为另一种示例，第二功率分配优先级顺序可以包括第一PUSCH的功率分配优先级高于以下中的至少一项功率分配优先级：承载CSI的PUCCH的功率分配优先级、承载CSI的PUSCH的功率分配优先级，且第一PUSCH的功率分配优先级低于以下中的至少一项功率分配优先级：承载HARQ-ACK信息和/或SR的PUCCH的功率分配优先级、承载HARQ-ACK信息的PUSCH的功率分配优先级。
此时，第二功率分配优先级顺序可以如下所示：
在PCell传输的PRACH；
承载HARQ-ACK信息和/或SR的PUCCH，或承载HARQ-ACK信息的PUSCH；
在PCell传输的第一PUSCH；
承载CSI的PUCCH或承载CSI的PUSCH；
未承载HARQ-ACK信息或CSI的PUSCH；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输。
作为另一种示例，第二功率分配优先级顺序可以包括第一PUSCH的功率分配优先级高于以下中的至少一项功率分配优先级：未承载HARQ-ACK信息的PUSCH的功率分配优先级、未承载CSI的PUSCH的功率分配优先级，且第一PUSCH的功率分配优先级低于以下中的至少一项功率分配优先级：承载CSI的PUCCH的功率分配优先级、承载CSI的PUSCH的功率分配优先级。
此时，第二功率分配优先级顺序可以如下所示：
在PCell传输的PRACH；
承载HARQ-ACK信息和/或SR的PUCCH，或承载HARQ-ACK信息的PUSCH；
承载CSI的PUCCH或承载CSI的PUSCH；
在PCell传输的第一PUSCH；
未承载HARQ-ACK信息或CSI的PUSCH；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输。
需要说明的是，在本申请实施例中，除了第一PUSCH，其他PUSCH，如未承载HARQ-ACK信息的PUSCH、未承载CSI的PUSCH、承载HARQ-ACK信息的PUSCH以及承载CSI的PUSCH都不属于第一消息。
可以看到，在该实现方式中，第一PUSCH的功率分配优先级较高，从而可以保证第一PUSCH的功率分配的优先级，避免了第一消息不能被网络 设备正确接收造成第一消息重传的问题，减少了两步随机接入过程的时延，并且也减少了上行干扰的随机接入资源的浪费。
在另一种实现方式中，终端设备可以根据第一消息的重传次数确定第二功率分配优先级顺序。其中，第一消息的重传次数也可以称为第一消息的功率攀升计数参数。
可选地，当第一消息的重传次数小于或等于阈值时，第二功率分配优先级顺序可以包括第一PUSCH的功率分配优先级低于预设功率分配优先级。
可选地，当第一消息的重传次数大于或等于阈值时，第二功率分配优先级顺序可以包括第一PUSCH的功率分配优先级高于预设功率分配优先级。如此，可以保证第一PUSCH的功率分配优先级较高，从而可以保证重传次数较高的第一消息的功率能够优先保证，保证第一消息可以尽快被网络设备成功接收。
其中，该阈值可以是基于协议预设在终端设备上的，或者，由网络设备预先配置给终端设备的，例如，可以通过RRC信令进行配置。
可选地，在本申请实施例中，预设功率分配优先级可以为以下中的至少一项功率分配优先级：
承载HARQ-ACK信息和/或SR的PUCCH的功率分配优先级；
承载HARQ-ACK信息的PUSCH的功率分配优先级；
承载CSI的PUCCH的功率分配优先级；
承载CSI的PUSCH的功率分配优先级；
未承载HARQ-ACK信息的PUSCH的功率分配优先级；
未承载CSI的PUSCH的功率分配优先级。
示例性地，若预设功率分配优先级为承载HARQ-ACK信息和/或SR的PUCCH的功率分配优先级，以及承载HARQ-ACK信息的PUSCH的功率分配优先级，且第一消息的重传次数小于或等于阈值，此时，第二功率分配优先级可以如下所示：
在PCell传输的PRACH；
承载HARQ-ACK信息和/或SR的PUCCH，或承载HARQ-ACK信息的PUSCH；
在PCell传输的第一PUSCH；
承载CSI的PUCCH或承载CSI的PUSCH；
未承载HARQ-ACK信息或CSI的PUSCH；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输。
再示例性地，若预设功率分配优先级为承载HARQ-ACK信息和/或SR的PUCCH的功率分配优先级，以及承载HARQ-ACK信息的PUSCH的功率分配优先级，且第一消息的重传次数大于或等于阈值，此时，第二功率分配优先级可以如下所示：
在PCell传输的PRACH，或在PCell传输的第一PUSCH；
承载HARQ-ACK信息和/或SR的PUCCH，或承载HARQ-ACK信息的PUSCH；
承载CSI的PUCCH或承载CSI的PUSCH；
未承载HARQ-ACK信息或CSI的PUSCH；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输。
或者，第二功率分配优先级可以如下所示：
在PCell传输的PRACH；
在PCell传输的第一PUSCH；
承载HARQ-ACK信息和/或SR的PUCCH，或承载HARQ-ACK信息的PUSCH；
承载CSI的PUCCH或承载CSI的PUSCH；
未承载HARQ-ACK信息或CSI的PUSCH；
SRS传输，其中非周期性的SRS的优先级高于半静态和/或周期性的SRS，或者在除PCell之外的服务小区上的PRACH传输。
应理解，本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本发明实施例，而非限制本申请实施例的范围。
在该实施例中，终端设备根据第一消息的重传次数或功率攀升计数参数的不同，设置第一消息中第一PUSCH的功率分配的不同优先级，优先保证了重传次数大的或功率攀升计数参数大的第一消息的功率分配，避免了第一消息由于功率压缩造成的更多次的重传，减少了两步随机接入过程的时延，减少了上行干扰和随机接入资源的浪费。
可选地，在本申请实施例中，当第一传输时刻的总发射功率大于终端设备的第一最大发射功率时，终端设备除了可以根据功率分配优先级顺序确定第一PUSCH的第一发射功率外，还可以根据其他方式确定第一PUSCH的第一发射功率。例如，终端设备可以根据第一PUSCH在第一传输时刻的信道质量，确定第一PUSCH的第一发射功率。
终端设备确定第一PUSCH的第一发射功率后，可以在第一传输时刻，基于第一发射功率向网络设备发送第一PUSCH。
在本申请实施例中，终端设备还可以确定第二发射功率，其中，第二发射功率可以为多个待发送信号中除第一PUSCH之外的每个待发送信号的发射功率；然后，终端设备可以基于第二发射功率，发送多个待发送信号中除第一PUSCH之外的待发送信号。
可选地，终端设备确定第二发射功率的实现方式可以与确定第一发射功率的方式相同，比如根据第二功率分配优先级顺序确定第二发射功率。终端设备根据第二功率分配优先级顺序确定第二发射功率的实现方式可以参考前述内容的描述，此处不再赘述。
可选地，终端设备确定第二发射功率的实现方式可以与确定第一发射功率的方式不同，只要第一传输时刻的总发射功率小于或等于终端设备的第一 最大发射功率即可。比如终端设备根据第二功率分配优先级顺序确定第一发射功率，根据第一传输时刻的信道质量确定第二发射功率。
本申请实施例，在两步随机接入中，当终端设备同一传输时刻发送多个信号，该多个信号包括第一消息中的PUSCH，且该多个信号的发射功率之和大于终端设备的最大发射功率时，终端设备可以根据功率分配优先级顺序确定第一消息中的PUSCH的发射功率，由于在功率分配优先级顺序中，可以将功率优先分配给优先级高的信号，而优先级低的信号的功率可能被压缩，从而可以有效地确定第一消息中的PUSCH的发射功率。
